Study shows that it works against both Asian and African strains of virus
The Hyderabad-based Bharat Biotech’s ‘killed Zika virus vaccine’ using an African strain has shown 100% efficacy against mortality and disease in animal studies, a study has shown. A ‘killed virus vaccine’ or ‘inactivated vaccine’ contains virus that has been grown in culture and then killed using physical or chemical processes.
The results of the study has been published in the Nature group journal Scientific Reports. Two doses (5 and 10 microgram) of the vaccine given through intramuscular route on days 0 and 21 to mice were found to protect the animals against Zika virus seven days after the second vaccination.
